DROP FUNCTION

Purpose

Use the DROPFUNCTION statement to remove a standalone stored function from the database.

Note:

Do not use this statement to remove a function that is part of a package. Instead, either drop the entire package using the DROPPACKAGE statement or redefine the package without the function using the CREATEPACKAGE statement with the ORREPLACE clause.

Specify the schema containing the function. If you omit schema, then Oracle Database assumes the function is in your own schema.

function_name

Specify the name of the function to be dropped.

Oracle Database invalidates any local objects that depend on, or call, the dropped function. If you subsequently reference one of these objects, then the database tries to recompile the object and returns an error if you have not re-created the dropped function.

If any statistics types are associated with the function, then the database disassociates the statistics types with the FORCE option and drops any user-defined statistics collected with the statistics type.
